The Bitcoin Core development team has released an important update to patch a major DDoS vulnerability in its underlying software that could have been fatal to the Bitcoin Network, which is usually known as the most hack-proof and secure blockchain. The DDoS vulnerability, identified as CVE-2018-17144, has been found in the Bitcoin Core wallet software, which could potentially be exploited by anyone capable of mining BTC to crash Bitcoin Core nodes running software versions 0.14.0 to 0.16.2. In other words, Bitcoin miners could have brought down the entire blockchain either by overflooding the block with duplicate transactions, resulting in blockage of transaction confirmation from other people or by flooding the nodes of the Bitcoin P2P network and over-utilizing the bandwidth. The vulnerability had been around since March last year, but the team says nobody noticed the bug or nobody was willing to incur the expense of exploiting it. According to the bitcoin core developers...

A Latvian hacker behind the development and operation of counter antivirus service "Scan4You" has finally been sentenced to 14 years in prison. 37-year-old Ruslans Bondars, described as a Latvian "non-citizen" or "citizen of the former USSR who had been residing in Riga, Latvia," was found guilty on May 16 in federal court in Alexandria, during which a co-conspirator revealed he had worked with Russian law enforcement. Bondars created and ran Scan4you—a VirusTotal like online multi-engine antivirus scanning service that allowed hackers to run their code by several popular antiviruses to determine if their computer virus or malware would be flagged during routine security scans before launching them into a real-world malware campaign. While legal scanning services share data about uploaded files with the antivirus firms, Scan4you instead informed its users that they could "upload files anonymously and promised not to share information about the...

The security and privacy issues with APIs and third-party app developers are something that's not just Facebook is dealing with. A bug in Twitter's API inadvertently exposed some users' direct messages (DMs) and protected tweets to unauthorized third-party app developers who weren't supposed to get them, Twitter disclosed in its Developer Blog on Friday. What Happened? Twitter found a bug in its Account Activity API (AAAPI), which is used by registered developers to build tools to support business communications with their customers, and the bug could have exposed those customers' interactions. The Twitter AAAPI bug was present for more than a year—from May 2017 until September 10—when the microblogging platform discovered the issue and patched it "within hours of discovering it." In other words, the bug was active on the platform for almost 16 months. "If you interacted with an account or business on Twitter that relied on a developer...

A security researcher has publicly disclosed an unpatched zero-day vulnerability in all supported versions of Microsoft Windows operating system (including server editions) after the company failed to patch a responsibly disclosed bug within the 120-days deadline. Discovered by Lucas Leong of the Trend Micro Security Research team, the zero-day vulnerability resides in Microsoft Jet Database Engine that could allow an attacker to remotely execute malicious code on any vulnerable Windows computer. The Microsoft JET Database Engine, or simply JET (Joint Engine Technology), is a database engine integrated within several Microsoft products, including Microsoft Access and Visual Basic. According to the an  advisory  released by Zero Day Initiative (ZDI), the vulnerability is due to a problem with the management of indexes in the Jet database engine that, if exploited successfully, can cause an out-out-bounds memory write, leading to remote code execution. An attacker m...

A high-severity vulnerability has been discovered in 4G-based wireless 4GEE Mini modem sold by mobile operator EE that could allow an attacker to run a malicious program on a targeted computer with the highest level of privileges in the system. The vulnerability—discovered by 20-year-old Osanda Malith , a Sri Lankan security researcher at ZeroDayLab—can be exploited by a low privileged user account to escalate privileges on any Windows computer that had once connected to the EE Mini modem via USB. This, in turn, would allow an attacker to gain full system access to the targeted remote computer and thereby, perform any malicious actions, such as installing malware, rootkits, keylogger, or stealing personal information. 4G Mini WiFi modem is manufactured by Alcatel and sold by EE, a mobile operator owned by BT Group— Britain's largest digital communications company that serves over 31 million connections across its mobile, fixed and wholesale networks. How Does the Attack...

Atlanta-based consumer credit reporting agency Equifax has been issued a £500,000 fine by the UK's privacy watchdog for its last year's massive data breach that exposed personal and financial data of hundreds of millions of its customers. Yes, £500,000—that's the maximum fine allowed by the UK's Data Protection Act 1998, though the penalty is apparently a small figure for a $16 billion company. In July this year, the UK's data protection watchdog issued the maximum allowed fine of £500,000 on Facebook over the Cambridge Analytica scandal , saying the social media giant Facebook failed to prevent its citizens' data from falling into the wrong hands. Flashback: The Equifax Data Breach 2017 Equifax suffered a massive data breach last year between mid-May and the end of July, exposing highly sensitive data of as many as 145 million people globally. The stolen information included victims' names, dates of birth, phone numbers, driver's licens...

The notorious hacking group behind the Ticketmaster and British Airways data breaches has now victimized popular computer hardware and consumer electronics retailer Newegg. Magecart hacking group managed to infiltrate the Newegg website and steal the credit card details of all customers who entered their payment card information between August 14 and September 18, 2018, according to a joint analysis from Volexity and RiskIQ . Magecart hackers used what researchers called a digital credit card skimmer wherein they inserted a few lines of malicious Javascript code into the checkout page of Newegg website that captured payment information of customers making purchasing on the site and then send it to a remote server. Active since at least 2015, the Magecart hacking group registered a domain called neweggstats(dot)com on August 13, similar to Newegg's legitimate domain newegg.com, and acquired an SSL certificate issued for the domain by Comodo for their website. A day l...

Windows and Linux users need to beware, as an all-in-one, destructive malware strain has been discovered in the wild that features multiple malware capabilities including ransomware, cryptocurrency miner, botnet, and self-propagating worm targeting Linux and Windows systems. Dubbed XBash, the new malware, believed to be tied to the Iron Group, a.k.a. Rocke—the Chinese speaking APT threat actors group known for previous cyber attacks involving ransomware and cryptocurrency miners . According to the researchers from security vendor Palo Alto Networks, who uncovered the malware, XBash is an all-in-one malware that features ransomware and cryptocurrency mining capabilities, as well as worm-like ability similar to WannaCry or Petya/ NotPetya . In addition to self-propagating capabilities, XBash also contains a functionality, which is not yet implemented, that could allow the malware to spread quickly within an organization's network. Developed in Python, XBash hunts for vul...
